Sigma asked me to sic Spirit Choco on their fursona in a sequence I'll be working on for them as part of their pledge rewards. Here it is basically getting carte blanche, root access, executive power over basically everything inside her head, though she is none the wiser.
It's gonna take a lot of restraint for it not to unlock everything and absolutely wreck her in one fell swoop, but a little subtlety will go a long way.
